PROBLEM TO BE SOLVED: To enable improvement of quality and increase of yield without generating voids in a molding resin part of a molded article by a reduced pressure molding using a low viscosity resin. SOLUTION: A switching control process is performed, wherein the process comprises a starting process of operating an air suction means 90 by passing-by a movable pin 62 from the channel of an air vent 60 in order to allow a control part to exhaust air in a cavity 12 and a pot 50 and further exhaust water in a molding resin 110 after supplying a molding resin 110 in a pot 50, a stopping process of stopping operation of an air supply-exhaust device 90 before the channel head of a molding resin 110 passes through a gate, a restart process of restart operation of the air supply-exhaust device 90 when the channel head of a molding resin 110 accesses a cavity 12, and a closing process of introducing a movable pin 62 into the channel of an air vent 60 when the channel head of a molding resin 110 is accessed to a place just in front of the air vent 60.
